Patent EP-0097753-B1 (EP)
IPC: H04L29/00
Filed: 1982-06-25
Granted: 1986-10-01
Abstract: A device for detecting the presence of an alarm tone of a given frequency within a received signal carrying digital data in addition to said tone. The receiver comprises an analog-to-digital converter (42) the output of which is applied to a first recursive bandpass filter centered at the frequency of the alarm tone and the feedback loop of which includes a limiter. In addition, an input feedforward loop is provided for adding (at 58) the output signal from the converter (42), as multiplied by a coefficient  gamma , to the output signal from the limiter. The output signal from the adder (58) is hard limited (at 44), then passed through a second bandpass filter. The energy of the signal obtained at the output of said second filter is then measured to provide indication of a tone's being received when said energy exceeds a predetermined threshold.

Title: Process for the production of pseudocumene or durene
IPC: C07C2/86
Filed: 1983-09-22
Granted: 1986-12-30
Abstract: A process for producing pseudocumene or durene is described, comprising methylating xylene by the use as a catalyst of a crystalline borosilicate. The specific crystalline silicate catalyst increases the conversion of xylene and the selectivity of pseudo-cumene or durene. The process of the invention can be performed either in one step or in two steps. The two-step reaction provides various industrial advantages, such as a high degree of utilization of the methylating agent and a great increase in the selectivity of the product.
